“But will Teach not anticipate all of this, and take pains to keep his fleet together?”

“In a well-disciplined fleet, pursuing Victory, that’s how it would go. But that is a pirate-fleet, in pursuit of plunder, and by the rules and account-books of piracy, the lion’s share goes to the ship that takes the prize.”

“Ah-so the captain of each ship has incentive to split away and attack us individually.”

“Just so, Dr. Waterhouse.”

“But would it not be foolhardy for a little sloop to engage a ship with all-this?” Daniel gestures down the length of the gundeck-a bustling bazaar where cannonballs, sabots, and powder-kegs, lies, promises, and witticisms are being exchanged lustily.

“Not if the ship is undermanned, and the captain a senile poltroon. Now, if you’ll just follow me down into the hold-don’t worry, I’ll get this lantern lit, soon as we are away from the gunpowder-there, that’s it. She’s a tidy ship, wouldn’t you agree?”

“Beg pardon? Tidy? Yes, I suppose, as ships go…” says Dr. Waterhouse, finding Dappa, sometimes, too subtle-an excess of quicksilver in the constitution.

“Thank you, sir. But ’Tis a disadvantage, when we have to fight with blunderbusses. The virtue of a blunderbuss, as you may know, is to make a weapon out of whatever nails, pebbles, splinters, and fragments might be lying about-but here on Minerva we make a practice of sweeping that matter up, and throwing it overboard, several times daily. At times like this we do regret that we neglected to hoard it.”

“I know more than you imagine of blunderbusses. What do you want me to do?”

“In a little while, one of the men’ll be teaching you how to fuze mortar-bombs-but we’re not quite ready for that just yet-now I would ask you to go down into the hold and-”

Dr. Waterhouse doesn’t believe, until he’s down there, what Dappa tells him next. He hasn’t seen the hold yet, and reckons it’ll be like the shambolic Repository at the Royal Society-but no. The great casks and bales are stacked, and lashed in place, with admirable neatness, and there is even a Diagram tacked to the staircase bulkhead in which the location of each object is specified, and notes made as to what’s stored there and when it was done. Underneath, under a subheading labelledbilge, van Hoek himself has scratched “out-moded china-keep handy.”

Dappa has pulled two sailors away from what they’ve been doing the last half-hour: standing by a gunport carrying on a learned discourse about an approaching pirate-sloop. The sailors considered this to be time well spent, but Dappa felt otherwise. These two spend a minute consulting the Diagram, and Daniel realizes with moderate astonishment that they both know how to read, and interpret figures. They agree that the out-moded china is to be found forward, and so that’s where they go-to the most beautiful part of the ship, where many ribs radiate from the up-curving keel, forming an upside-down vault, so it’s like being a fly exploring the ceiling of a cathedral. The sailors move a few crates out of the way-they never stop talking, each trying to outdo the other in bloodcurdling yarns about the cruelty of certain infamous pirates. They pull up a hatch that gives access to the bilge, and in no time at all two crates of markedly ugly china have been fetched out. The crates themselves are handsome productions of clear-grained red cedar, chosen because it won’t rot in the wet bilge. Into them the china has been thrown with no packing material between items, so part of Daniel’s work is already done. He thanks the two sailors and they look back at him queerly, then return abovedecks. Daniel spreads an old hammock-two yards of sailcloth-on the planking, tips a crate over, and then attacks its spilled contents with a maul.

What is the optimal size (he wonders) of a shard of pottery for firing out of a blunderbuss? When the King’s guards shot him before his father’s house during the Fire, he was knocked down, bruised, cut, but not really penetrated. Probably the larger the better, which makes his job easier-one would like to see great sharp triangles of gaudily-painted porcelain spinning through the air, plunging into pirate-flesh, severing major vessels. But too large and it won’t pack into the barrels. He decides to aim for a mean diameter of half an inch, and mauls the plates accordingly, sweeping chunks that are the right size off into small canvas bags, raking bigger ones toward him for more punishment. It is satisfying, and after a while he finds himself singing an old song: the same one he sang with Oldenburg in Broad Arrow Tower. He keeps time with his hammer, and draws out those notes that make the cargo-hold resonate. All round him, water seeps through the cracks between Minerva ’s hull-planks (for he is well below the water-line) and trickles down merrily into the bilge, and the four-man pumps take it away with a steady suck-and-hiss that’s like the systole and diastole of a beating heart.

The Inquisitive Jesuit RICCIOLI has taken great pains by 77 Arguments to overthrow the Copernican Hypothesis… I believe this one Discovery will answer them, and 77 more, if so many can be thought of and produced against it.

DANIEL SPENT A GOOD PARTof two months on the roof of Gresham’s College, working on a hole-making, not mending, one. Hooke could not do it because his vertigo had been acting up, and if it struck while he was on top of the College, he would plunge to the ground like a wormy apple from a tree, his Last Experiment a study into the mysterious power of Gravitation.

For a man who claimed to hate the appearance of sharp things when viewed under a microscope, Hooke spent a great deal of time honing jabs at Inquisitive Jesuits. While Daniel was up on the roof making the hole, and a rain-hatch to cover it, Hooke was safe at ground level, running up and down a gallery. Strapped into his groin was a narrow hard saddle, and projecting from the saddle a strut with a wheel on the end, geared to a clock-work dial: a pedometer of his own design, which enabled him to calculate how much distance he had covered going nowhere. The purpose-as he explained to Daniel and diverse other aghast Fellows of the R.S.-was not to get from point A to point B, but to sweat. In some way, sweating would purge his body of whatever caused his headaches, nausea, and vertigo. From time to time, he would stop and refresh himself by drinking a glass of elemental mercury. He had set up a table at one end of the gallery where he stockpiled that and several of Mons. LeFebure’s fashionable medicines. There were various sorts of quills, too. Some of them he used to tickle the back of his throat and induce vomiting, others he sharpened, dipped in ink, and used to note down data from his pedometer, or to vent his spleen at Jesuits who refused to admit that the Earth revolved around the Sun, or to sketch out plans for Bedlam, or to write diatribes against Oldenburg, or simply to transact the routine business of the City Surveyor.

The Inquisitive Jesuit Riccioli had pointed out that if the heavens were sown with stars, some near and some far, and if the Earth were looping round the Sun in a vast ellipse, then the positions of those stars with respect to one another should shift during the course of the year, as trees in a forest changed their relative positions in the eyes of a traveler moving past. But no such parallax had been observed, which proved (to Riccioli, anyway) that the Earth must be fixed in the center of the Universe. To Hooke it only proved that good enough telescopes hadn’t been built, nor precise enough measurements made. To obtain the level of magnification he needed, he had to construct a telescope 32 feet long. To annull the light-bending effects of the Earth’s atmosphere (which were obvious from the fact that the Sun became an oval when it rose or set), he had to aim it straight up-hence the demand for a vertical shaft to be bored through Gresham’s College. Gresham’s antique mansion was now like an ancient plaster wall that had been mended so many times it consisted entirely of interlocked patches. It was solid scar tissue. This made the work more interesting for Daniel, and taught him more than he’d ever cared to know about how buildings were put up, and what kept them from falling down.
